The LAX VFR corridor is great. I flew overhead LAX when I was there last summer. You can fly through the overhead of the airport by setting a transponder code (maybe 1201, can't honestly remember though) flying a set altitude (a set altitude depending on your direction of flight, NW or SE) and just position reporting on the LAX Special Flight Rules Area Unicom frequency. It is a strange feeling to be flying over one of the busiest airports in the world without having to speak to ATC to do so. There is also a shoreline and hollywood route through the LAX class B airspace but you obviously you must be cleared to fly through it.
